Abstract
1,239,351. Programmed control; fluid regulation. LUMMUS CO. Aug. 5, 1969 [Aug. 5, 1968,] No.39223/69. Headings G3H, and G3N. An unwanted signal, such as a noise level signal, Fig. 1, is removed from a wanted signal such as a batch information signal slowly varying about a steady process value, by applying the information signals from a source 2, Fig. 2, to an input 10. The input 10, which is an electric conductor or a fluid communicating conduit, is connected at a junction 12 to lines 14, 16 connecting, respectively, to an electronic fluidic or pneumatic linear amplifying device 4 and an electronic or, fluidic or pneumatic non-linear amplifying device 6. The device 6 incorporates rate feedback with respect to a selectable time constant whereby the information signal is reduced and only the noise level signal appears on an output line 24. The output from device 4 on a line 20, and the output on line 24 are fed to an electronic, fluidic or pneumatic differential amplifier 8, the output from which, on a line 26, comprises only the batch information signal which is fed to a process controller, not shown. It is stated that the elements of Fig. 2 can be electronic and fluidic inter-connected by interposed transducers.
